BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to a solid waste burner or furnace or incineration plant, and more particularly to a solid waste burner including a reduced and simplified structure for allowing the waste burner to be easily built everywhere, and including a structure for allowing the waste or the refuse to be burned with decreased energy, and including a structure for greatly reducing the air pollution problems.

2. Description of the Prior Art

Various kinds of typical solid waste burners or furnaces or incineration plants have been developed and comprise a burner or combustion chamber for receiving the waste or the refuse and for burning the waste or the refuse.

For example, U.S. Pat. No. 3,543,702 to Appelhans discloses one of the typical methods and apparatuses for burning of refuse and comprising a circular path for successively guiding the waste or the refuse to move through a drying zone, a burning zone, and a cooling zone, for allowing the waste or the refuse to be continuous guided to combustion air and to be burned.

However, normally, the typical solid waste burners or furnaces or incineration plants comprise a large volume that may not be built or constructed in local or downtown area. In addition, the combustion gas or the burned air or the combustion ash will fly everywhere such that the typical solid waste burners or furnaces or incineration plants also may not be built or constructed in local or downtown area.

U.S. Pat. No. 4,098,200 to Dauvergne discloses another typical low pollution solid waste burner comprising a first combustion chamber for partially oxidizing the waste or the refuse, a second combustion chamber for further oxidizing the waste or the refuse, and a conduit provided between an ash compartment and the first combustion chamber for completely oxidizing the ash compartment gases.

However, similarly, the typical solid waste burners or furnaces or incineration plants also comprise a large volume that may not be built or constructed in local or downtown area, and the combustion gas or the burned air or the combustion ash also may not be completely filtered or treated and will also fly everywhere such that the typical solid waste burners or furnaces or incineration plants also may not be built or constructed in local or downtown area.

U.S. Pat. No. 4,449,924 to Ceretti discloses a further typical industrial furnace comprising a chamber with refractory walls to which energy is supplied by electric means and/or by combustion and into which the material to be treated is charged. However, the combustion gas or the burned air or the combustion ash generated by the typical industrial furnace also may not be filtered or treated and will fly everywhere such that the typical solid waste burners or furnaces or incineration plants also may not be built or constructed in local or downtown area.

U.S. Pat. No. 6,453,829 to Tsai et al. discloses a still further typical incinerator assembly having waste smoke treating device and comprising a complicated structure for treating the waste smoke. The typical incinerator assembly also comprises a large volume that may not be built or constructed in local or downtown area where territory or land may not be easily obtained.

The present invention has arisen to mitigate and/or obviate the afore-described disadvantages of the conventional solid waste burners.
